I would highly discourage this too since it adds complication to = the fuel=20 system and I have not identified a real idle problem to begin = with. The=20 latest version of the EC2 has differential injector flow rates so you = could use=20 smaller primaries and larger secondaries if idle was a big = concern. The=20 RX-8 (Renesis) uses this arrangement.

Every instance of idle problems that I have looked at so far was = due to=20 either bad EC2 setup or injector location (far from port).

How about 3 injectors per rotor with progressive staging? = This sure=20 would require a BUNCH of wires though!

I don't recommend it but I do make a single injector version of = the EC2=20 now. Still waiting on reports on the two already = shipped.

Replying=20 to my own e-mail- after I posted the drawing, I = continued to=20
mess with the design and came up with a solution which is = simply to=20
angle the injector bosses and leave the fuel rail=20 straight. This will
allow me to use both = injectors. The=20 revised drawing is attached.
